Back at home, safe and sound.  No further incidence of the illuminated oil
light after an oil change, and remove, clean and reinstall of the
same O.P.R. spring and valve.

-Was it the oil change?  Is there an intermittent short that is yet to be
found, compounded by the rain?  Was there some crud keeping the OPR from
closing?  Will this recur as soon as the new oil begins to break down?

-Thanks for your comments.  Lots to delve into.

-I'm thinking about an oil pressure gauge.

Cheers,
gab
